◆ Webcam can be operated from Chrome
Some webcams allow you to freely change the orientation and zoom, but APIs have been put in place to operate those cameras from Chrome.
In order to use this API, it is necessary to acquire not only camera usage authority but also operation authority.
The detailed implementation method can be confirmed
◆ Allow service workers to handle range requests properly
By adding the 'Range' header to the HTTP request, it is possible to download only a specific part when downloading large-sized content such as audio and movies, and this function can pause / resume the download, and It is used to improve the quality of streaming.
Since the Range header is deleted when accessing through the service worker, it was necessary to write exception handling properly and skip the request directly, but from Chrome 87, the Range header will be maintained even through the service worker. Now you don't have to write extra code. However, at the time of writing the article, the Firefox service worker still deletes the Range header, so it seems that it is not okay to remove the exception handling suddenly.
◆ Developer tool updates
-Easy debugging of grid display
A 'grid' tag is displayed on the grid element so that it can be identified at a glance. You can also visually view the grid settings for that element by clicking 'grid'.
・ Simulation of WebAuthn is possible
WebAuthn is a system that allows you to authenticate with a physical device without using a password. Starting with Chrome 87, an emulator has been added that allows you to test without having to prepare a physical device.
